"TestNG Essentials"
TestNG Essentials provides a comprehensive, in-depth exploration of the TestNG testing framework, empowering Java quality engineers and automation architects to master the full lifecycle of test development, execution, and integration. The book begins by situating TestNG within the historical evolution of Java testing tools, contrasting it with JUnit, and elucidating its robust architecture and annotation-based execution model. Through clear explanations and practical guidance, readers gain a solid understanding of core TestNG concepts, advanced annotation strategies, suite design, and configuration nuances essential for effective, maintainable test automation.
Building on these foundations, TestNG Essentials offers advanced coverage of data-driven testing, parallel and distributed execution, and performance optimization. Readers will learn how to leverage TestNG's powerful features for scalable pipeline integration—ranging from parameterized and factory-generated tests to isolation of test data in parallel environments, cloud-based scaling, and resource contention management. The text meticulously demonstrates how to weave TestNG into modern DevOps and CI/CD workflows, automate reporting and artifact publishing, and enforce quality gates for rigorous, enterprise-grade testing.
The book culminates with expert discussion of TestNG's extension points—including listeners, reporters, and plugins—as well as real-world patterns, anti-patterns, and best practices for sustainable test development at scale. Readers benefit from hands-on strategies for web, API, and microservice automation, integration with open-source and enterprise tools, and maintaining compliance in regulated environments. Whether building the first automated suite or refining mature, cloud-native pipelines, TestNG Essentials is the authoritative resource for professionals seeking to unlock the full potential of TestNG for modern software delivery.
